时光吹老了好少年岁月染旧了凄少女
[shí guāng chuī lăo le hăo shăo nián suì yuè răn jiù le qī shăo nǚ]
It depicts aging over time affecting young men and women differently. Boys become mature ('good youth') whereas girls turn melancholic ('sorrowful girls') because they've been shaped by experiences and the passage of time.
